CARL JOSEPH, OF BAYONNE, NEW JERSEY, ASSIGNOR OF ONE-HALF TO FREDERICK J. KLOES,

OF JERSEY CITY, NEW JERSEY.

To all whom it may concern:

Be it known that I, CARL JOSEPH, a citizen of the Empire of Germany, residing in Bayonne, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvementsin Fasteners for Shade- Brackets, of which the following is a specification.

This invention relates to improvements in fasteners for shade-brackets.

In fireproof buildings the windoW-casings are made of sheet-steel which is pressed into the proper sha e. The ordinary shadebrackets cannot window-casings by the ordinary screws or nails.

The object of this invention is to supply a fastener for shade-brackets for use with metallic window-casings; and for this purpose the invention consists of a fastener for shadebrackets composed of two interlocking spring tongues which are provided with curved ends that are passed through the usual holes in the base of the shade-bracket and through registering holes drilled into the window-casing, the outer ends of the springtongues being interlocked with retaining catches so as to form a reliable attaching device for the shade-bracket.

In the accompanying drawings, Figure l represents a front-elevation of a shadebracket showing my improved fastener in position for attaching it to a metallic windowcasing, and Fig. 2 is a side-elevation of the same partly in section on line 2, 2, Fig. 1.

Similar letters of reference indicate corresponding parts in both figures.

Referring to the drawings, a represents a sheet-metal window-casing with which my improved shade-bracket is to be used. The shade-bracket t is of the usual construction, stamped up from sheet metal of suitable thickness and provided in its bracket-portion with a hole b1 for the pivot of the springroller and with the usual `holes b2 in the baseportion.

The fastening device by which the shadebracket is attached to the metallic casing ct Specification of Letters Patent.

is composed of two separate spring-tongues d, which are preferably made of wire of suitable thickness and of a suflicient length to extend from one fastening hole to the other. Each spring-tongue d is bent near its fastening hole b2 into a laterally-extending U- shaped catch d1 and a curved extension d2, which latter is bent from the inner end of the catch approximately into line with the main portion of the spring-tongue. The free end of each spring-tongue d is placed under the bent U-shaped catch Z1 of the other springtongue after the curved ends d2 are passed through the holes b2 in the shade-bracket and the holes o drilled into the metallic windowcasing, whereby the spring-tongues are held firmly in position parallel with and sidewise of each other, as shown in Fig. l. The tension exerted by the interlocked springtongues on the curved inner ends presses them firmly against the inner surface ofthe sheet-metal casing, so that the bracket is rigidly held in position ready for receiving the spring-roller of the window-shade.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. The combination, with a window-casing having fastening holes, of a shade-bracket having fastening holes to register with said first-named holes, and separate springtongues passing through said holes so as to hold the parts together' and having means whereby said tongues are interlocked with each other.

2. A fastener for shade-brackets comprising two separate spring-tongues, each having a curved end and a catch for retaining one end of the other spring-tongue.

3. A fastener for shade-brackets comprising two separate interlocking spring-tongues, each having a straight end, a curved end and an intermediate catch.

4. The combination, with a metallic window-casing provided with fastening holes, of a shade-bracket provided with holes in its base-portion registering with the holes in the casing, and two interlocking spring-tongues provided with Curved ends that pass through With and With a oatoh adapted to look the 10 the holes in theshade-braoket and Windowother end of the other spring-tongue.

easing to the inside of the latter and with In testimonyythatl claim the Aforegoing as catches for looking the opposite ends of the my invention, I have signed my name 4in spring-tongues. presence of two subscribing Witnesses.

5. A fastener for shade-braokets, consist- CARL JOSEPH. ing ol' two interlocking spring-tongues, eaeh Witnesses: spring-tongue being provid'ednvith a curved PAUL GOEPEL,
